Please note: Theme options pages are not standard in WordPress anymore. It is highly recommended that you move all your theme settings in the Customizer.
We do have a Theme Customizer Framework as well to make your workflow easier. Check it out here: https://github.com/istefan/wpshed-theme-customizer
Details and instructions here: https://wpshed.com/wordpress/wordpress-theme-customizer-framework/
However, if you'd like to include a Theme Options page, there's more information about how to implement it here: WPshed Theme Options.
